-- I) Introduction and Explanations : A Roamer Rematch Bug

The roaming Latios and Latias are known to have bugged IVs in RS and RfVf, but there is another bug that concerns them in RS.
I'll use an example to illustrate it.

Example :
- You go in Trainer Tower, and face this team :
Kingdra / Salamence / Dugtrio / - / - / -

- After a good battle, you lose agains the last Pokemon of the opponent.
When you lost, the opponent team was :
KO Kingdra / KO Salamence / Dugtrio / - / - / -

 Once a battle ends, the game doesn't refresh or erase the data concerning the opponent's Pokemon, so this data will stay here for a certain amount of time.

Now if you went to Route 101 and made an encounter with a Poochyena, the opposing party Pokemon would be :
Poochyena / - / - / - / - / -

But if you used Repel and went to meet your roamer (let's say Latias) in order to not make a single wild/trainer battle between your loss at Trainer Tower and the roamer battle, the opposing party Pokemon during your Latias battle would look like this :
Latias / KO Salamence / Dugtrio / - / - / -

 To put it shortly, the game doesn't erase the data on opponent party slots 2,3,4,5,6 when you meet a roaming Latias/Latios in Ruby and Sapphire.
It only puts Lati@s on the first slot and stops there, whereas it normally also cleans the remaining party slots.

So, if there were alive Pokemon in opponent party slots 2 to 6 (like on the example), what would happen if you were to kill the roamer ?

The answer is :
- The next alive Pokémon in the opposing party will be sent, like a "normal" battle.

The game acts as you would have imagined for a trainer battle, but since wild battle are supposed to be against a single Pokémon, it is a bit hard to believe/understand at first that another Pokemon can be "sent" during a wild battle.

 Thus, you can rebattle the remaining Pokemon of your last opponent using this glitch.
And since this "rematch" happens during a roamer battle, you can use Balls in order to catch the opposing Pokemon !

Advantages :
- You can steal a Pokemon from nearly every trainer in the game, as long as it isn't in first place.
- This allows you to steal Trainer Tower Pokemon for shinyhunting !

Inconvenients :
- You need to have a roaming Lati@s in your save.
If you killed/caught the Lati@s, you will have to make a new save or use another RS cartridge as there is no way for now to revive a roamer in RS.
- It doesn't work in Emerald, Fire red, or Leaf Green.
- You can only catch one Pokemon with this bug.
Since you're rebattling Pokemon during a roamer battle, catching a Pokemon during that fight will end the battle and the roamer will be considered "caught", so you'll never be able to meet it again.

If you have an Action Replay or are on emulator, you can use codes or savestates in order to get another roamer and catch multiple Pokemon with this bug.
- Nearly every stolen Pokemon will become Bad Eggs.
Almost every trainer in the game will have a different ID and SID that yours.
When you steal one of their Pokemon, their ID and SID is changed to yours.
However, since most of the Pokemon data is crypted using the Trainer ID and SID, that change of ID/SID completely messes up the encryption, which makes the game unable to decrypt the Pokemon data correctly.
This encryption issue will cause an anti-cheating script to detect an irregularity, and this will transform the Pokemon in a Bad Egg.
A Bad Egg is basically an Egg that never hatches, which means that you can't do anything with it.

Even if you use Pomeg Glitch in order to send a Bad Egg in a fight, you wouldn't get anything interesting from it (apart from nice glitches due to the Glitch Moves the Bad Egg has).

/!\ The only Pokémon in RS that won't become Bad Eggs when stolen are the Pokemon from Trainer Tower, which is why this bug is specifically tied to Trainer Tower.

- The Pokémon are hard to steal without a Master Ball.
Since this bug involves a roamer fight, every Pokemon you will rebattle during that fight will act like a roamer : they will try to flee unless you prevent them from doing that.
I made a capture team that works for many Trainer Tower Pokémon (check Notes below), but it doesn't manage Pokémon with Self-destruct/Explosion/Quick Claw + OHKO Move.




-- II) Trainer Tower Hunting

- Material -
- Super Repels / Max Repels
- A Pokémon with Illuminate (Volbeat, Chinchou, Lanturn, Staryu, Starmie)
- A Lv 36-40 Pokémon that has 103 speed or more and that can kill a Latios/Latias.
This Pokémon can know Mean Look/Spider Web/Block and Baton Pass in order to trap the roamer, and then send a stronger Pokémon to kill it. (Smeargle, Ariados and Umbreon are the only ones who can do that)(For Ariados and Umbreon, you need to paralyze the roamer beforehand)
- A Pokémon team to fight in Trainer Tower and easily lose too (see Notes for more details)
- A Pokémon team to catch your Shiny Pokémon during the roamer battle (see Notes for more details)
- A Master Ball
You can also only use that to catch the Shiny and not bother making a capture team.
- Other Balls
- Fluffy Tails
- An Emerald version and a link cable (not necessary but very very useful)
- Knowledge about Pomeg Glitch (See Notes) (not necessary but very very useful)
- Material for Pomeg Glitch on your Emerald version (not necessary but very useful)
You can use Pomeg Glitch to make the matches and capture way less tricky.


0) Have a RS save file with an alive roamer (not caught, not killed).
If you haven't generated your roamer yet, generate it. (You can leave the roamer non-generated if you want to hunt it later, but it is easier to find the roamer when it is already generated)
Beat Routes 110,117,118 trainers.

1) If the roamer isn't in your Pokédex, encounter it.
You need the dex entry of the roamer to accurately track it.
(You can encounter the roamer without its Pokédex entry, but this will take longer.)

~~ Encountering a Roamer without its Pokédex entry :
1.1) Make a party with : KO Staryu/Chinchou/Volbeat with Illuminate - Lv 36-40 alive Pokémon - other Pokémon
1.2) Fly to Slateport and go to Route 110 South
1.3) Use Repels, use Acro Bike, and go into the patches of grass near the cycling road entrance
1.4) Cycle for 15-20 steps in the grass.
-- If Latias/Latios appears, flee. Now you're done
-- If they didn't appear, enter the cycling road, exit it, and repeat steps 1.3) and 1.4) until you meet one.

Each time you go enter and exit the cycling road door, the roamer is randomly replaced in one of the 20 routes he can be on, so you have 1/20 chance to get in on Route 110.
Thus, it will take 4-5 minutes in average to encounter it.
~~


2) Fly to Trainer Tower. Take your team for Trainer Tower, and start doing matches.
Here, you will need an Emerald version in order to make a team that is able to win matches quickly and easily.
I really recommend you to do this. (on console or emulator)

2.0) Obtaining a Swampert with specific Glitch Moves
The best Pokémon to use in RS Trainer Tower is :
Swampert holding Lum Berry
OHKO Glitch Move (0x0947) - Change Battle Type Move (0x044C) - Surf - Hail

Check the Notes below to see how to obtain that Pokémon with Pomeg Glitch.
Obtain this Pokémon in Emerald by using Pomeg Glitch, then trade it to your RS version.


2.1) During each match, check if one of the opponent's Pokémon is shiny.
You can either kill the opponent's Pokémon, or use a move like Whirlwind/Roar to see all of them.
However, using Whirlwind/Roar is more tedious and brings some complications, so I recommend you to kill everything that isn't Shiny.

If you have made the Swampert from Pomeg Glitch, things will be easier :
Use Hail against Shedinja.
Use Surf against Sturdy Pokémon.
Use OHKO Glitch Move against the remaining Pokémon.
If your Swampert ges hurt, you can use Bag Items to heal it. (You can do that thanks to Change Battle Type Move)

2.2) If the opponen't doesn't have any shiny, reset or win the match.
After a certain amount of wins the oppnent will use stronger Pokémon (including legendaries) and these Pokémon will have better IVs (up to full 31 IVs) which is interesting.

If you don't have a powerful team, you can reset and redo the first Trainer Tower matches.


2.3) If the opponent's second or third Pokémon is shiny, lose your match without killing the shiny.
- If you have obtained Swampert, use a Fluffy Tail to flee and lose the match.

/!\ As the first opponent's Pokémon can't be stolen, it it appears shiny, that will be an uncatchable shiny. This means that you have a 1/3 chance to get an uncatchable shiny on this hunt.
/!\ If you kill the shiny, it won't appear again using the Roamer Rematch Bug.
/!\ Check the moves that the Shiny possesses, as it can have a suicidal move. (See Notes below)

2.4) Fly to Mauville City, and take your capture team.
Have a Pokémon with Surf too.
Put the Lv 36-40 Pokémon first, and use Acro or Mach Bike.


3) Encountering a RS Roamer with its Pokédex entry
This strategy can also be used to shinyhunt RS roamers.
It is the fastest strategy to see them, and takes an average of 3min30 when well executed.
It involves the "Mauville Cross", the gathering of Routes 110,111,117, and 118, because they communicate with each other with Mauville City and because they are at the border of the Routes where a roaming Latias/Latios can be.

3.1) At Mauville City, open your Pokédex and check the roamer location.
If the roamer isn't on Route  110/111/117/118 / 119/123/134, go to Route 110.

3.2) Go in and out cycling road, checking the roamer location everytime you go back to Route 110, until the Roamer ends up on Route 110/111/117/118 / 119/123/134.

3.3)
 If you are on Route 110/111/117/118 and if the roamer is on Route 110/111/117/118, go on the roamer's Route, then use Pokédex to check the roamer's location.

If you are on Route 110 and if the roamer is on Route 119/123, then go to Mauville City and use Pokédex. (Not if Route 134)
If you are on Route 111 and if the roamer is on Route 123/134, then go to Mauville City and use Pokédex. (Not if Route 119)
If you are on Route 118 and if the roamer is on Route 119/134, then go to Mauville City and use Pokédex. (Not if Route 123)
If you are on Route 117 and if the roamer is on Route 119/123/134, then go to Mauville City and use Pokédex.


 If you are at Mauville City and if the roamer is on Route 110/111/117/118, go to  Route 110 or 117 (Route 117 if he is on Route 110), then use Pokédex to check the roamer's location.

If you are at Mauville City and if the roamer is on Route 119 :
 -If you came from Route 111, go to Route 118, then use Pokédex to check the roamer's location.
 -If you didn't come from Route 111, go to Route 111, then use Pokédex to check the roamer's location.

If you are at Mauville City and if the roamer is on Route 123 :
 -If you came from Route 118, go to Route 111, go back to Mauville City, then go to Route 118, and use Pokédex to check the roamer's location.
 -If you didn't come from Route 118, go to Route 118, and use Pokédex to check the roamer's location.

If you are at Mauville City and if the roamer is on Route 134 :
 -If you came from Route 110, go to Route 118, go back to Mauville City, then go to Route 110, and use Pokédex to check the roamer's location.
 -If you didn't come from Route 110, go to Route 110, and use Pokédex to check the roamer's location.

If you are at Lavandia/Route110/111/117/118, and if the roamer isn't on Routes 110/111/117/118/ 119/123/134, go back to step 3.2).

/!\ Be careful about trainers in Routes 110,117,118, and about Repel's lenght when surfing !

3.4) Once you are on the same road as the roamer, use Repel and go into the grass/water to make it appear.

4) Use your capture team to Kill the roaming Latios/Latias.
Once the roamer is killed, one of the Pokémon from the previous battle that was in party slots 2 to 5 and that was still alive will be sent.

4.1) If the sent Pokémon isn't the Shiny, kill it too.
This will be much harder to do because that Pokémon will be at Lv50/100, and will be much stronger than a wild roamer.

Here having an Emerald version and something to trade is useful in order to quickly make Pokémon capable of trapping a Lv 100 Pokémon that wants to flee, and capable of killing/weakening it.

4.2) Now, the Shiny is sent into the battle.
/!\ Check again the moves of the Shiny to see if it doesn't have dangerous moves.
Trap it with Mean Look/Block/Spider Web and weaken it before throwing Balls, or throw a Master Ball to avoid any dangerous move.

5) Save.
And now, you have successfully retreived your Shiny from Trainer Tower, congratulations !!

 ~~~~ Capture team for the Roamer Rematch Glitch :
This is the team that I used. It covers many cases, but requires 3 Pokémon. Way simpler teams can be made if you don't mind throwing a Master Ball.
Ariados : Focus Band, Lv 40, Swarm
- Spider Web
- Baton Pass
252 HP, 252 SpDef EVs

Absol : Lv 5, Pressure
- Baton Pass
- Double Team
- Substitute

Gardevoir : Leftovers, Lv 100, Trace
- Substitute
- Hypnosis
- Mean Look
- Icy Wind
252 HP, 126 Def, 126 SpDef EVs

- Way to use this team :
Paralyze the roamer before beginning the hunt. (Ariados is too slow else)

Use Lv 40 Ariados for the Repel Trick to encounter the Roamer.
Use Spider Web to trap the Roamer, then Baton Pass to Absol.
Absol is of Dark type, so Lv40 Latias and Latios can't hurt it. Use Substitute, Double Team, X Defend, X Accuracy, X Speed to boost yourself.
Once you are boosted, Baton Pass to Gardevoir. Use Icy Wind to kill the roamer.
Then, a Trainer Tower Pokémon comes. Use Mean Look to trap it.
 If it isn't the Shiny, use Hypnosis and Icy Wind to kill it. (Use Substitute if the substitute breaks).
 If it is the Shiny and if it possesses a dangerous move (Explosion, Selfdestruct, Whirlwind, Roar), throw a Master Ball.
 If it is the Shiny, use Hypnosis and throw Balls. With your high defense and accuracy, you can throw at least 400 Balls before the Shiny kills itself with Struggle.

~~ Other strategies :
 Lv 40 Smeargle with more than 103 Speed, Mean Look/Block/Spider Web + Baton Pass. (Block the roamer, then use Baton Pass to send a strong Pokémon. Kill the roamer, then Master Ball the shiny).
 Lv 40 Pokémon with 1 HP, more than 103 speed, and Endeavor + Quick Attack. (Before beginning the hunt, encounter the roamer and use Endeabor to put it to 1 HP. Then, when you meet a shiny and encounter the roamer again, use Quick Attack to finish it. After that, Master Ball the shiny.)
